pull replication + firewalls
hey all,
i was trying to pull down a db from a remote server via pull replication to
my laptop. now, it's windows, and therefore suspect, but this may be
something else. when i attempt pull replication initiated from windows 0.91
laptop to ubuntu 0.10 server, it crashes with this stack:
[error] [<0.103.0>] {error_report,<0.22.0>,
{<0.103.0>,crash_report,
[[{pid,<0.103.0>},
{registered_name,[]},
{error_info,
{exit,
{badarg,
[{ets,lookup,
[ibrowse_lb,
{"server removed to protect the innocent",<port
number>}]},
{ibrowse,send_req,6},
{couch_rep,do_http_request,5},
{couch_rep,get_db_info,1},
{couch_rep,init,1},
{gen_server,init_it,6},
{proc_lib,init_p_do_apply,3}]},
[{gen_server,init_it,6},{proc_lib,init_p_do_apply,3}]}},
{initial_call,{couch_rep,init,['Argument__1']}},
{ancestors,
[couch_rep_sup,couch_primary_services,couch_server_sup,<0.1.0>]},
{messages,[]},
{links,[<0.53.0>]},
{dictionary,[]},
{trap_exit,true},
{status,running},
{heap_size,610},
{stack_size,23},
{reductions,320}],
when i decided to try to push from the ubuntu server to the laptop (ports
5984 was opened on both attempts), everything went swimmingly. this last
part makes me think that may be this is a firewall issue of some sort. for
pull replication, do the dbs attempt to talk over any port other than 5984
(or whatever is configured locally)?
thanks,
alex.

Before anything, have yout ried turning off the windows firewall and
testing the pull to make sure the problem isn't with the Firewall? I'm
only asking because you say it went well with the other pull so one
wonders :)

I'm guessing this is a bug in the Windows startup script. It needs to
execute ibrowse:start(), but it hasn't. The firewall doesn't appear
to play a role at all. The reason push replication works is that your
Ubuntu machine is making the HTTP requests, so ibrowse on the Windows
machine is not involved. And

Nope, they don't. Best, Adam
